Unity3D如何實(shí)現(xiàn)攻擊范圍檢測(cè)

 //要攻擊的目標(biāo)

 //扇形距離 攻擊距離 扇形的半徑

 //扇形的角度 也就是攻擊的角度

  //玩家正前方的向量
  Vector3 norVec = transform.rotation * Vector3.forward;
  //玩家與敵人的方向向量

  //求兩個(gè)向量的夾角
  float jiajiao = Mathf.Acos(Vector3.Dot(norVec.normalized, temVec.normalized)) * Mathf.Rad2Deg;
  if (distance < SkillDistance)
